Understanding the interaction of thiosulfate with Alloy 800 in aqueous chloride solutions using SECM

In situ scanning electrochemical microscopy (SECM) and scanning tunneling microscopy (STM) assisted scanning reference electrode technique (SRET) were applied for the first time to study the interaction of thiosulfate with Alloy 800 surfaces in aqueous chloride solutions. Electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM) were also performed to understand the interaction mechanism. The results showed that the effect of 0.075 mol/L thiosulfate in 0.6 mol/L chloride solutions strongly depended on the potential. There was no aggressive effect at the corrosion potential where the passive layer was intact, but a combined effect was observed with the presence of chloride ions at high potential where the passive layer was broken down.

Nanoparticles based on retinoic acid caped with ferrocenium: A novel synthesized targetable nanoparticle both with anti-cancer effect and drug loading capacity

To date, there is an urgent need for cancer treatment to improve in many ways in order to successfully cure all cancers. Retinoic acid (RA) is a promising anti-cancer drug through influencing cancer stem cells (CSCs). Taxol is a chemotherapy drug for many cancers. To increase the anti-cancer effects of RA and taxol, we created a novel RA nanoparticle, FCRAN, which has the ability of carrying a second anti-cancer drug, taxol, using nanotechnological methods. The results of this study demonstrated that this RA nanoparticle was water-soluble and retained the same effects as RA on cancer cells, such as inhibiting the proliferation of CSCs, inducing the differentiation of CSCs, and enhancing the sensitivity of CSCs to chemotherapeutic drugs. In addition, this RA nanoparticle can be used to carry a second anticancer drug, taxol, to become FCRAN/T and synergistically enhance the anti-cancer effects of both drugs in vivo. Interestingly, the FCRAN/T is a targetable anti-cancer nanoparticle in the presence of higher levels of glutathione (GSH) in cancer cells. Our results demonstrate that our novel synthesized nanoparticles not only retain the RA functions, but can also carry a second anticancer drug to play a synergistic anticancer role with good water solubility, in particular FCRAN/T can target cancer cells. Therefore, our novel synthesized targetable anti-cancer nanoparticles have a better application prospect than that of RA or taxol alone.

Scanning electrochemical microscopy: Surface interrogation of adsorbed hydrogen and the open circuit catalytic decomposition of formic acid at platinum

The surface interrogation mode of scanning electrochemical microscopy (SECM) is extended to the in situ quantification of adsorbed hydrogen, H ads, at polycrystalline platinum. The methodology consists of the production, at an interrogator electrode, of an oxidized species that is able to react with Hads on the Pt surface and report the amounts of this adsorbate through the SECM feedback response. The technique is validated by comparison to the electrochemical underpotential deposition (UPD) of hydrogen on Pt. We include an evaluation of electrochemical mediators for their use as oxidizing reporters for adsorbed species at platinum; a notable finding is the ability of tetramethyl-p-phenylenediamine (TMPD) to oxidize (interrogate) H ads on Pt at low pH (0.5 M H2SO4 or 1 M HClO4) and with minimal background effects. As a case study, the decomposition of formic acid (HCOOH) in acidic media at open circuit on Pt was investigated. Our results suggest that formic acid decomposes at the surface of unbiased Pt through a dehydrogenation route to yield Hads at the Pt surface. The amount of Hads depended on the open circuit potential (OCP) of the Pt electrode at the time of interrogation; at a fixed concentration of HCOOH, a more negative OCP yielded larger amounts of Hads until reaching a coulomb limiting coverage close to 1 UPD monolayer of H ads. The introduction of oxygen into the cell shifted the OCP to more positive potentials and reduced the quantified Hads; furthermore, the system was shown to be chemically reversible, as several interrogations could be run consecutively and reproducibly regardless of the path taken to reach a given OCP.

Transition metal cation and phosphate anion electrochemical recognition in water by new polyaza ferrocene macrocyclic ligands

New polyaza ferrocene macrocyclic ligands 4-7 have been synthesised and with 4, copper(II) and nickel(II) transition metal complexes isolated. Electrochemical investigations reveal these redox-active ligands can electrochemically sense various transition metal cations in polar organic solvents and in water at high pH values with ligands 4 and 5. Aqueous electrochemical competition experiments with Ni2+, Cu2+ and Zn2+ suggest 4 and 5 exhibit a selectivity preference for the copper(II) cation. At lower pH values (6-8) the respective protonated polyammonium forms of 4, 5 and 7 complex and electrochemically detect the biologically important phosphate anions, ATP and hydrogen phosphate in the aqueous environment.

Additive-manufactured (3D-printed) electrochemical sensors: A critical review

Additive manufacturing or three-dimensional (3D)-printing is an emerging technology that has been applied in the development of novel materials and devices for a wide range of applications, including Electrochemistry and Analytical Chemistry areas. This review article focuses on the contributions of 3D-printing technology to the development of electrochemical sensors and complete electrochemical sensing devices. Due to the recent contributions of 3D-printing within this scenario, the aim of this review is to present a guide for new users of 3D-printing technology considering the required features for improved electrochemical sensing using 3D-printed sensors. At the same time, this is a comprehensive review that includes most 3D-printed electrochemical sensors and devices already reported using selective laser melting (SLM) and fused deposition modeling (FDM) 3D-printers. The latter is the most affordable 3D-printing technique and for this reason has been more often applied for the fabrication of electrochemical sensors, also due to commercially-available conductive and non-conductive filaments. Special attention is given to critically discuss the need for the surface treatment of FDM 3D-printed platforms to improve their electrochemical performance. The insertion of biochemical and chemical catalysts on the 3D-printed surfaces are highlighted as well as novel strategies to fabricate filaments containing chemical modifiers within the polymeric matrix. Some examples of complete electrochemical sensing systems obtained by 3D-printing have successfully demonstrated the enormous potential to develop portable devices for on-site applications. The freedom of design enabled by 3D-printing opens many possibilities of forthcoming investigations in the area of analytical electrochemistry.

Synthesis and metallation of ferrocenylimines derived from ligating diaminoheteroarenes

A regioisomeric mixture of 1,1?-didodecylferrocenedicarbaldehydes 3 was prepared from the reaction of a regioisomeric mixture of 1,1?-didodecyldilithioferrocenes and dimethylformamide. Three ligating heteroaromatics were synthesized each containing two amino substituents: 5,5?-diamino-2,2?-bipyridine and 5,5?-diamino-2,2? : 6?,2?-terpyridine were prepared from appropriate dinitro compounds by reduction with palladium on charcoal-hydrazine hydrate. The reaction of 2-cyano-5-nitropyridine and hydrazine hydrate gave an isolable amidine derivative and this was transformed with hydrazine in a separate reaction under more forcing conditions into 3,6-bis(5-amino-2-pyridyl)-1,2-dihydro-1,2,4,5-tetrazine. The latter was converted into the tetrazine by oxidation (2,3-dichlpro-5,6-dicyano-1,4-benzoquinone) and then trifluoroacetylated [(CF3CO)2O] to give the bis(trifluoroacetylamino) derivative. Diels-Alder reaction of the latter with dodec-1-yne afforded 4-n-decyl-3,6-bis[5-(trifluoroacetylamino)-2-pyridyl]pyridazine which was deprotected (K2CO3) to give the corresponding diamine. Bis(ferrocenyl) Schiff bases were prepared from ferrocenecarbaldehyde and the appropriate diamine in either uncatalysed or acid-catalysed condensations. Tetracarbonylmolybdenum complexes were prepared by treating the appropriate diamines with molybdenum hexacarbonyl. Reaction of one of these complexes with ferrocenecarbaldehyde gave a heterobimetallic complex.

Structural influences on the electrochemistry of 1,10-di(hydroxyalkyl) ferrocenes. Structure of [Fe{h5-C5H4eCH(OH)e(CH2)3OH}2]

Abstract A series of 1,1′-di(hydroxyalkyl)ferrocenes, [Fc'{(CH 2)nOH}2], with n = 1 (1), 2 (2), 3 (3) and 4 (4) and Fc’ = Fe(eta5-C5H4)2, was synthesized. The electrochemistry of the di(hydroxyalkyl)ferrocenes was studied by cyclic voltammetry in CH2Cl2/0.1 M [N nBu4][PF6] utilizing a glassy carbon working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential, Eo’ , inversely proportional to alkyl chain length and approximately 59 mV smaller than those of the corresponding mono(hydroxyalkyl)ferrocenes derivatives [Fc(CH2)mOH] with m = 1 (1m), 2 (2m), 3 (3m), and 4 (4m) and Fc = Fe(eta5-C 5H5)(eta5-C5H4 -). The tetraalcohol [Fc'{CH(OH)(CH2)3OH} 2], 5, possessing four OH functionalities, two in the terminal positions and two more, one on each of the two alpha-C relative to the ferrocenyl (Fc’ for dialcohols or Fc for monosubstituted derivatives) group, was isolated as a side product during the synthesis of 4. The formal reduction potential of 5 was Eo’ = -24 mV vs. FcH/FcH+ and closely approached Eo’ of [FcCH(OH)CH3] (Eo’ = -11 mV), [Fc'{CH(OH)CH3}2] (-21 mV) and 1 (0.00 mV vs. FcH/ FcH+). The single crystal X-ray structure of the tetraalcohol 5 (Z = 8, orthorhombic, space group Pbca) was also solved.
